Lugo made the long trip down from Galicia to Andalucía to square off against relegation-threatened Córdoba but were unable to return home with anything to show as they played most of the second half with ten men following Fede Vico’s expulsion and lost a goal 11 minutes from time.
The Lugiño had a strong showing in the league and were impressive in their win against Granada last week, but this loss hands them their third in four matches.
The hosts thought they had gone ahead when defender Aythami Artiles found the net with a header but the assistant rightly flagged him for offside, along with Sergio Guardiola.
Moments into the second half, Lugo were reduced to ten after Vico picked up his second yellow. Contesting an aerial ball against Edu Ramos, the midfielder was penalised for jumping with his left arm across his opponent.
Looking to make the extra man advantage count, Córdoba pushed forward and had the ball in the net again, but Guardiola had strayed into an offside position to undo some great work on the right hand side by right back Miguel Loureiro to play him in.
The visitors did not take the expulsion lying down and almost fashioned the opening goal themselves. Córdoba needed goalkeeper Pawel Kieszek to look lively to turn away a superb freekick from Antonio Campillo hit from 25 yards out.
Loureiro again was causing problems for Lugo down the right flank. He played a neat ball in which Lugo failed to clear and they had keeper Juan Carlos to thank as he patted away a rasping drive from close range by substitute Mario Barco.
However, the visitors resolve was broken on 79 minutes. This time a ball came in from the left and Guardiola timed his run right this time to capitalise and claim his 16th goal of the campaign. They could have had more in the closing stages but a fine double save from Juan Carlos kept the deficit at a single goal.
Lugo drop two places to 11th and Córdoba remain in 20th.
